I have no idea what point you are attempting to make. Non-power users don't need full-blown version control, there are plenty of more straight-forward ways of making sure users don't lose their data than that. Save-as is not mutually exclusive with automated backup systems, or undo systems.

Furthermore, nobody is forbidding them from using the tools "power-users" use. The only difference between power users and regular users is what tools they choose to use.

Do you believe the solutions we have today are decent enough and cannot be improved further? I wish handling files was so simple that even those you call “non power-users” (i.e. pretty much everyone) could work with versioned files.

Note that I am neither saying it's easy nor that it is appropriate for every program. But it is definitely possible: http://www.apple.com/macosx/whats-new/auto-save.html

"I wish handling files was so simple that even those you call “non power-users” (i.e. pretty much everyone) could work with versioned files."

We have that already, it's called persistent undo and/or save as. Stunningly, a versioning system designed for the technologically illiterate doesn't measure up to one designed for coders.

Auto-save is a separate issue, but we have that as well...
